Frigidaire Refrigerator Ice Maker Overflow:... | appliancefaults.com

Technical Background:

The ice maker's Main Control Unit (MCU) manages the water fill cycle and ice ejection. The MCU sends a 120V AC signal to the water inlet valve solenoid, opening the valve to fill the ice maker mold. The ice level sensor tells the MCU when to stop filling. A faulty sensor or valve can cause overfilling. Thermistors are used to determine when the ice is ready to be harvested.

Symptoms:

US homeowner is reporting their Frigidaire refrigerator's ice maker is overflowing, resulting in a large block of ice forming in the ice bin and surrounding area. The ice dispenser may also be jammed or inoperable due to the frozen mass.

Possible Causes:

Faulty Ice Maker Module - The module may be malfunctioning, causing it to overfill the ice mold.
Defective Water Inlet Valve - The valve might not be closing completely, leading to continuous water flow.
Clogged or Frozen Fill Tube - An obstruction in the fill tube can cause irregular water flow and overflow.
Low Water Pressure - Insufficient water pressure can affect the fill time and lead to overflow.
Damaged Ice Level Sensor - The sensor may not be accurately detecting the ice level, causing continuous filling.
Thermistor Malfunction - Ice not harvesting and overflowing the unit.

Solution:

1

Disconnect power to the refrigerator at the breaker panel. Verify 0V AC at the refrigerator receptacle using a multimeter.
2

Remove the ice maker assembly. Use a 1/4-inch nut driver or socket to remove mounting screws.
3

Inspect the fill tube for ice blockage. Use a hair dryer on low heat to gently thaw any ice. Alternatively, use a turkey baster with hot water.
4

Examine the water inlet valve. Disconnect the water line and inspect for debris. Using a multimeter, test for continuity across the solenoid coil. A lack of continuity indicates a faulty valve. If accessible, test the voltage to the valve during the ice fill cycle (approximately 120V AC).
5

Inspect the ice maker module. Look for visible signs of damage or wear. Test the ice level sensor for proper operation.
6

Check water pressure to the refrigerator. Ensure it meets the manufacturer's minimum requirement (typically 20 PSI). Install a pressure regulator if needed.
7

Reassemble the ice maker and reconnect power. Monitor ice production. Allow 24 hours for the ice maker to stabilize.

Safety Warning:

Always disconnect power to the refrigerator before performing any repairs. Lock Out / Tag Out (LOTO) procedures must be followed. High voltage is present in the appliance; exercise caution.

Prevention:

Replace the refrigerator's water filter every 6 months. Periodically inspect the fill tube for ice buildup and clear as needed. Monitor ice production and address any irregularities promptly.

Expert Tip:

Some Frigidaire models have a service mode accessible through the control panel. Consult the service manual for the specific model to access diagnostic codes and test functions.

Frequently Asked Questions

•What is the correct resistance reading for the thermistor at room temperature (70°F)?

The resistance value varies by model, but typically falls within the range of 5k to 10k ohms. Consult the service manual for your specific model.

•How can I manually force the ice maker to cycle to test its operation?

Some ice makers have a test button located on the module. Press and hold the button for a few seconds to initiate a harvest cycle. Refer to the service manual for specific instructions.

•Where is the water inlet valve located, and how do I access it?

The water inlet valve is usually located at the back of the refrigerator, near the bottom. Access typically involves removing the rear access panel, using a 5/16-inch socket or nut driver.
